New Cooler for Canon cameras with flippy screen

[gregbradley]

This new product looks to be a sophisticated cooling solution from Tilta:

I imagine its likely it will fit other models than the new R5.

Making one to go on the outside of a camera would be easy. I think my home made cooler cost only $20. Any cooling is good cooling I suppose and my camera is weather sealed. Might try it and see if an L bracket would hold a cooler to the tripod mount.

Do you have a photo of your cooler?

One guy who does Sony mods puts a copper cold finger that runs from behind the sensor to the mounting plate of the camera.

Now you could attach a cooler to that and it would remove some of the heat.

I presume the heat is mainly from the processor and a bit from the sensor and battery?

Hi Greg, if you have a metal bodied camera, usually they're magnesium or other alloy, you can fashion an outboard Peltier and/or cooler. You just need to get a look at the inside of the camera to see if you have a good heat conduction path from the tripod socket to the sensor plate. The Nikon D800 and D810 are good candidates for it, but for instance the Nikon D600 is not. I think the canon EOS R SERIES use magnesium alloy bodies partly so you might be in luck. I like to look at disassemble videos or pictures from sites like fixmycamera or similar.

One important caveat would be not to cool too much,
certainly not lower than the dew point of the air in the camera otherwise condensation may result.

Right.

This Tilta cooler has a temperature sensor and won't cool too much.

The cooler consists of peltier device, a metal plate , a heat sink and a fan.
The aluminium plate in my case goes against the surface to be cooled and The peltier is clamped between that and the aluminium heat sink with thermal grease and surrounded by equal to peltier thickness EPDM insulation gasket.

I used a fan and heat sink from an old computer power supply and processor .

Takes the camera down below 6 degrees but chews up a lot of amps so better to stick to 12 degrees. Mine is 12a.

( edit: Of course that is on a metal astro camera. On a DSLR I think you would need some clever mods)

I don't wish to stifle the excitement that DSLR cooling discussions usually generate, but will point out that there is a substantial archive of threads that dive deep into the subject, and discuss what actually works and how to go about it. Search is your friend. The expert, in my opinion, is still Rowland (rcheshire).
Search for his threads. I have a couple of build threads in the archive as well.
Do some research before you throw money at external fan mounts, they have a poor history.
